| 内容記述 | In order to provide a valuable greener product using agricultural waste, polymer/ agricultural waste composites has been fabricated. Since, however, the incompatibility between the hydrophilic natural fiber and hydrophobic polymer matrices makes it difficult to disperse the individual fiber throughout polymer matrices, and the incorporation of agricultural waste into polymer matrices may compromise certain mechanical properties. In order to improve the compatibility between natural fiber and polymer matrices, this thesis is studied and discussed the control of surface property using compatibilizer and vapor phase assisted surface polymerization for the high-performance polymer/ agricultural waste composites. This thesis is composed of up to Chapter 5 from Chapter 1. The background, scope and objectives of this study are described in the introduction Chapter 1. In Chapter 2, in order to investigate potential of agricultural natural fiber as filler, I focused on Erianthus arudinaceus as a cellulose resource crop because of high CO_2 fixation efficiency. Polymer composites of polypropylene (PP) with Erianthus fiber (ETF) were fabricated and they were evaluated by mechanical properties to reveal the compatibility between PP and ETF. To overcome poor compatibility between PP and ETF, Maleic anhydride-modified polypropylene (MAPP) was applied as a compatibilizer. Since ETF/PP/MAPP composites improved the mechanical properties, it is revealed that interfacial property control between matrices and natural fibers is critical. In Chapter 3, vapor-phase assisted surface polymerization (VASP) method was applied as an alternative approach to compatibilizer. The VASP is not only a surface coating method for fabrication of composites but it is also expected to be able to apply to a wide range of substrates. VASP is an excellent method for preserving the fine structures of delicate substrate surfaces such as biomaterials in comparison with liquid and melting processes. After the diffusion and adsorption on the substrate surfaces, the monomer can be polymerized.. VASP of MMA onto wheat straw fiber (WSF) was applied to modify the surface property and improve the compatibility between PLLA and WSF. Bio-composites with biodegradable polymer (poly (L-lactic acid) (PLLA)) and WSF was fabricated via VASP. Since the PLLA/VWSF (treated with VASP in WSF) composites improved in tensile strength (20-30%) compared with that of PLLA/WSF composites, VASP proved to improve the compatibility between matrices and natural fibers. In Chapter 4, the gas-flow type of vapor-phase assisted surface polymerization (VASP-F) was successfully developed since the substrate surface could be polymerized through monomer mist produced by monomer bubbling. VASP-F can inherit advantages of VASP method due to polymer grafted on substrate, and can recover non-reactant monomer. Larger amounts of substrate can be modified by VASP-F compared to VASP. In conclusion, the improvement of compatibility between natural fiber and polymer matrices are essential to produce the high-performance polymer/agricultural waste composites. This study provides new approach for the natural fiber reinforced plastics. The utilization of agricultural waste as filler for biocomposites would lead to the sustainable society throughout the achievement of environment conservation, and the social system encourage the agricultural sector revitalization. | |||||||||
